Abstract (en)
[origin: EP2708736A2] A load and noise mitigation system (40) for attachment to a wind turbine blade (20). The system (40) includes a flex member (42) for attachment adjacent the trailing edge (28) of the blade (20) and a noise reduction member (44) associated with the flex member (42). At least a portion of the flex member (42) is configured to deform and change in orientation from a first position (58) to a second activated position (60) in the presence of an air pressure force on at least a portion of the flex member (42).
